Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
The zeros is another name for solutions.
x^2 - 5x - 1 = 0
You must use the quadratic formula to find x.
In the formula, a = 1, b = -5 and c = -1.
Plug into formula and solve for x.
The values of x are the zeros of the function.
Answer:
468.75 / 125 = $3.75 per car wash.
Step-by-step explanation:
Answer:
The answer is 67 degrees.
Step-by-step explanation:
The angle x is supplementary with 23 degrees because that angle is an alternate interior. Recall that is within a right angles as well so
90 - 23 = 67
(negative square root two)/2, (negative square root two)/2
